The number of lollipops that Anna had in the end is repeated. Make the number of lollipops that Anna had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Cindy had less than Anna
= 18 u - 3 u
= 15 u
15 u = 75
1 u = 75 ÷ 15 = 5
Number of lollipops that Anna had at first
= 18 u
= 18 x 5
= 90
Answer(s): 90
